Did you know?

In addition to standard NIC drivers, the U25 adapter also supports Onload kernel bypass to provide both TCP and packet-based APIs for network application acceleration. The Xilinx Onload software accelerates and scales network-intensive applications such as in-memory databases, software load balancers, and web servers. With Onload, data centers can support 400% or more users on their cloud network while delivering improved reliability, enhanced quality of service (QoS) and higher return on investment, without modification to existing applications.

Features

The Xilinx Alveo U25 25GbE SFP28 2-Port PCIe FPGA Adapter offers a number of features, including the following:

A Powerful SmartNIC

The U25 delivers ultra-high throughput, small packet performance and low-latency. The host interface supports standard NIC drivers as well as Onload kernel bypass to provide both TCP and packet-based APIs for network application acceleration. IEEE1588v2 precision timing protocol (PTP) is provided for applications that require synchronized time stamping of packets with single-digit nanosecond accuracy.

A Programmable Fabric

The U25 SmartNIC contains a programmable FPGA handling all network flows. Each flow can be individually delivered to the host and/or streamed in hardware to through bump-in-the-wire network acceleration functions and/or compute acceleration kernels for application processing within the FPGA.

A Platform for Hardware Accelerated Clouds

Cloud service providers are deploying SmartNIC fabrics to achieve virtual switching and micro- segmentation of services that scale linearly with CPU cores and network links.
